- The document outlines the goals, outcomes, prerequisites, topics covered, and grading for a compiler design course.
- The major goals are to provide an understanding of compiler phases like scanning, parsing, semantic analysis and code generation, and have students implement parts of a compiler for a small language.
- By the end of the course students will be familiar with compiler phases and be able to define the semantic rules of a programming language.
- Prerequisites include knowledge of programming languages, algorithms, and grammar theories.
- The course covers topics like scanning, parsing, semantic analysis, code generation and optimization.
In this PPT we covered all the points like..Introduction to compilers - Design issues, passes, phases, symbol table
Preliminaries - Memory management, Operating system support for compiler, Compiler support for garbage collection ,Lexical Analysis - Tokens, Regular Expressions, Process of Lexical analysis, Block Schematic, Automatic construction of lexical analyzer using LEX, LEX features and specification.

Compiler Construction
Phases of a compiler
Analysis and synthesis phases
-------------------
-> Compilation Issues
-> Phases of compilation
-> Structure of compiler
-> Code Analysis
Its the first phase of the compiler,useful in generating lexemes ,tokens and matching of the pattern.Its helpful in solving GATE/ UGCNET problems.For more insight refer http://tutorialfocus.net/
Translation of a program written in a source language into a semantically equivalent program written in a target language
It also reports to its users the presence of errors in the source program
We have learnt that any computer system is made of hardware and software.
The hardware understands a language, which humans cannot understand. So we write programs in high-level language, which is easier for us to understand and remember.
These programs are then fed into a series of tools and OS components to get the desired code that can be used by the machine.
This is known as Language Processing System.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
